The
Proportions of a Head

Although
the proportions of a head will vary from person to person
and change slightly with age, there are some basic principles
you can follow to improve your drawing. You can use
these to check the general size, shape and position
of features in your drawings.
If
you view a head from the front, its width is approximately
two thirds of its height.
If
you view a head from the side, its width is approximately
seven eighths of its height.
The
proportions of the head can be divided horizontally
into four equal quarters.
1.
The first quarter measures from the top of the head
down to the hairline.
2. The second quarter measures from the hairline down
to the eyes in the middle of the head.
3.
The third quarter contains most of the features. At
the top of this section the eyes
are usually level with the ears,
and at the bottom the nose
is roughly level with the ear lobes.
4. The final quarter stretches from the base of the
nose to the chin with the mouth
positioned just above the halfway mark.
These
proportions will only work if we share the same eye
level as the subject. They will become distorted if
we view the head from above or below.
Many
artists start a portrait with the eyes as they are the
focal point of any face. The following proportions should
help you with their scale and position in relation to
the other features.
The
eyes are situated approximately half way down the head.
If
you view a head from the front, the distance across
the eye is similar to the distance between the eyes.
The distance between the eyes is similar to the breadth
of the nose.
As
you can see from the illustration above, these distances
work out at approximately one fifth of the width of
the face.
Note
the position of the ear
in the profile view. It sits to the left hand side of
the vertical line which bisects the head.

If
you view a head from the front,
a triangle drawn from the centre of the head through
either side of the nose will establish a good proportion
for the breadth of the mouth.
If
you view it from the side, note how the eyes,
nose
and mouth
fit into a rectangle whose diagonal creates a good line
to position the corners of the nose and mouth.
